Judy's patterns are indeed gorgeous but I don't think I would recommend them to a beginner unless you took a class specific to her patterns. Just getting the pattern and looking at the pages of directions is enough to intimidate the most seasoned paper piecer. Of course you could do it but you may end up discouraged and frustrated to try some of hers as a beginner. Better to feel comfortable and consider yourself an intermediate so you have fun as well as end up with a beautiful quilt instead of WIP crammed into the corner of the closet.
I agree with luvspaper that you would do better to find some free patterns on the internet that are a bit more complex like New York Beauty or some of the free patterns on Silver linings originals and Carol Doak's websites.

If you feel comfortable with some of the more complex patterns offered on these sites then by all means try a Quiltworx pattern.
